ARTHUR MCDOUGALL DUCKHAM, OF ASHTEAD, ENGLAND.

DISCHARGING VERTICAL RET ORTS.

Application filed July 28, 1915.

1 '0 all whom it may concern:

Be it known that l, ARTHUR MoDoUcALL Diriuun, a subject of the Kingof Great Britain, residing in Ashtead, England, have invented certain new and useful Improvements in Discharging Vertical Retorts, of which the following is a specifica tion.

My invention relates to a method of discharging through a water seal, a vertical retort wherein coal or the like is continu- T he method consists in imparting areciprocating 'or oscillatory movement to a water trough which forms theseal and wholly or partially supports the charge of the retort, and in completely 'or partially preventing the material in the trough from sharing this movement in one direction so that at each movement some of'the material leaves the trough and fresh material descends into the trough. There are several manners in which this method may be applied. For instance the lower end of the retort or an extension thereof may extend into. a water trough mounted to rock on a suitable axis, there being sufiicient room between the end of therctort or \tension and the bottom of the trough forimssage of the carbonized material. Be-

of the retort or extension there is a stationary plate or the like acting as a scraper in relation to the bottom of the trough. When the trough is oscillated by a suitable mechanism the carbonized material is carried with it by the movement in one direction and a free space is left between the material and the scraper into which some of the charge in the retort descends. while during the movement in the other direction the scraper prevents the material from moving with the trough so that some of the material falls over the edge of the scraper on a. line bisecting or substantially bisecti'ng the discharge opening of the retort or extension, the; movement of the trough in eac direction becomes effective in discharging the When the scraper is flush with one side of the retort, in which case it may be an extension of the side or the longer side of an obliquely out discharge opening, the movement of the trough in one direction only is effective for discharg ing from the trough.

In theaccompanying drawing Figure 1 is a vertical section through a water trough into which the lower end of a retort ex;

tends; Fig. 2 is a similar view of a modified construction. In Fig. 1 the trough A is supported so as to oscillate about the hinge B. D is the lower end of the retort, which extends below the water seal C. E is a scraper secured to the retort. .\s the trough is caused to swing to the left as shown in full lines, the carbonized material is discharged over the right edge, and whenthe trou h is swung to the right as shown in dotted lines, the material is discharged over the left edge of the trough. Also, at each oscillation some of the charge falls into the trough.

In Fig. 2 the trough A, is adapted to receive a reciprocating motion on the rollers F, instead of an oscillatory motion, and in this example one side G of the retort is extended to act as a scraper. It is obvious that when the trough is moved to the left, some of the carbonized material is discharged over the right edge of the trough, and that when tile trough is moved to the right some of the charge falls from the retort into the trough.

Having thus described the nature of the said invention and the best means I know of carrying the same into practical efiect,

I claim 1- 1. Means for dlscl' arging carbonized ma terial from a vertical retort, comprising in combination a trough forming a water seal for the retort, means for imparting a toa'nd-=fro movement to the said trough, and means for preventing this movement from being fully imparted to' the material in the trouglhi.

2. cans for discharging carbonized material from a vertical retort, comprising in combination a trough forming a water seal for the retort, means for imparting a, to and-fro movement to the said trough and a stationary scraper in the trough adapted to prevent the movement of the trough from bein fully imparted to the material therein.

3. cans for discharging carbonized material from a vertical retort, comprising in combination a trough forming a Water sea for the retort, means for imparting a, to-

andfro movement to the said trough and a stationary scraper secured to the ertical retort and adapted to prevent the movement of the trough from being fully imparted to the material therein.

4:. Meansfor discharging carbonized material from a vertical retort, comprising in combination a trough forming a Water seal for the retort, means for imparting a toandfro movement to the said trough and a stationary scraper in the trough, substantially-bisecting the discharge opening of the retort whereby the movement of the trough in each direction becomes effective in discharging the carbonized material.

5. .Means for dischargingearbonized material from a Vertical retort, comprising in combination a trough pivoted about a horizontal axis and forming a Water seal for the retort, means for imparting an oscillatory motion to the trough about the said axis and means for preventing this movement from being fully imparted to the material in the trough.

6. Means for discharging carbonized material. from a vertical retort, comprising in combination a trough pivoted about a horizontal axis and forming a water seal for the retort, means for imparting an oscillatory motion to the trough about the said axis, and a stationary scraper, s!lbstantiall biseetiug the discharge opening" of the retort, whereby the movement of the trough in each direction becomes effective in discharging the carbonized material.
